GRAIN SEPARATOR AND SCOURER.

SPECIFICATIONorming part of Letters Patent No. 311,727, dated February 3, 1885.

Application filed August 19, 1884. (No mr de'J Ohio, have invented new and useful lmprove ments in Grain Separators and Sconrers, of which the following is a specification.

This invention relates more particularly to that class of separating-machines in which an inclined screen is employed in connection with an elevating mechanism, whereby the material which has passed over the screen is elevated and delivered on the top of the screen, and at the same time gradually moved across the screen, so that the material in passing from the inlet to the outlet side of the machine is-repcatedly elevated andcaused to iiow over the Y inclined screen.

The object ot' my invention is to improve the construction ot' this class of machines, whereby the grain is freed from the dust, chati', and other light impuritiesA by means ot' aircurrents passingthrongh the machine, and to combine therewith a suitable scouring and cleaning` device, whereby the wheat or other grain is thoroughly scoured and cleaned bet'ore leaving the machine,

My invention consists, to these ends, ofthe improvements in the construction ot'` the machine,whichwillbehereinafterfnllydcscribed, and pointed out in the claims.

In4 the accompanying drawings, consisting of four sheets, Figures 1 and 2 are end elevations ot my improved machine. Fig. 3 is a vertical cross-section through the feed end of the machine. Fig. i is a horizontal crosssection ofthe machine in line x rv, Fig. 8. Fig. 5 is a vertical crosssection through the discharge end ot' the machine. Fig. l is a horizontal cross section in line 1/ y, Fig. Fig. 7 is a side elevation of the machine. Fig. S is a perspective view on an enlarged scale of one ofthe scouring-plates. Fig. isafragmentary top plan view on an enlarged scale ofthe scour* ing mechanism.

Like letters of reference refer in the several igures.

A represents the frame or casing of the maf chine. composed of the upright posts a, horizontal cross-pieces a, and suitable boards secured thereto, the whole forming atight casing.

B represents the inclined screen covered with bolting or wire cloth, and arranged in the casing A and extending across the machine.

b represents inclined guide-boards or angleto like parts plates, arranged near the tail end of the screen and secured to a board, b', extending across the tail of the screen. The guide-boards b are inclined in such a direction as to deflect the material toward the discharge side of the cas ing ormachine, whereby the materia-lv is grad ually moved from the receiving toward the discharge side of the casing.

O represents the elevating mechanism arranged in the casing A, with its ascending and descending sides on opposite sides of the inclined screen B. The elevating mechanism C consists of endless belts or chains c and buckets o fastened thereto. The chains or belts c run around pulleys or sprocket-wheels c2, arranged in the corners oi' the'casing, so that the ascending and descending sides and bottom portion ot' the elevator are parallel With the upright sides and bottom of the casing.

The buckets o of' the elevator run close to the bottom of the casing, so as to pick up the material which falls on said bottom and elevate the same.

D represents a scouringeylinder arranged below the tail end ofthe screen B, and rotating in a concave or `emicirenlar trough, D'. The cylinder D is composed of circular plates d, which are each provided with a central hub or collar, d. and are secured to a. shaft, di, by

set-screws di". The circularA plates d are provided with grooves or corrugations cl, which are arranged radially, or nearly so, as shown in Fig. 8. The corrugations d" are arranged on both sides ot` the plates, and extend from the annular ribs di to the periphery of the plate. The trough D is provided with sectional scouring-plates e, having radial corrugations or grooves e ou both sides, similar to the corrugations on the circular plates d.. rlhe plates c are semicircular in form, and rest with their outer peripheral edges in contact with the concave surface ofthe trough D. rlhe plates e are provided on their ends or corners with lugs or ears e2, which rest upon the upper edges of the trough D, and are secured to the trough by bolts or screws passing through the lugs c. The plates o are arranged transversely in the trough D between the circular plates D, which latter revolve freely in the spaces between the plates c, as clearly shown in Figs. 4 and 9. The upper edges ofthe plates c are conca-ved, to allow the circular plates d, with their hubs d', to extend in the trough between the plates c, so that the peripheral edges of the circular plates will be close to the concave surface of thetrough, and the corrugated faces of the plates d will be opposite the corrugations on the plates e.

F represents a brush-cylinder secured to a shaft, f, and arranged on one side of the scour! ing-cylinder D and parallel therewith. F is a concave corrugated platevarranged below the brush F and in contact therewith. The concave F' is preferably composed of a number of round rods or bars, f fastened at their ends to curved end plates, f", `which are se,- cured to the casing of the machine. The upper edge of the concave F is preferably connected to the upper edges of the concave trough D', between the scouring-cylinder and the brush-cylinder, whereby the material as it escapes from the scouring-cylinder is caught bythe brush and conveyed between the brush and concave F. The concave F is connected at the discharge end of the machine with a discharge-spout g. The rods or barsf' are preferably indented or grooved on their upper surfaces, whereby theends of the grains can be acted upon by the brush F. The rods f are arranged close together, so as to prevent the kernels of wheat from passing through them.

H represents a sh akin g-shoe arranged above the casing of the machine and secured to the frame by spring-arms la h. The shoe H is provided with one or more screens, h', whereby thegrainis freed from sticks, straw, cockle, or other foreign matter, before entering the machine.

I represents the feed-spout ofthe machine, which communicates at its upper end by a spout, i, with the shoe H, and at its lower en d withan air-trunk, J, through which the grain passes before it is delivered into the machine. From the air-trunk J the grain drops into the spoutj, and through an opening, j', in the casing onto the bottom of the 1nachine.- The air-trunk J extends upward and across the machine, and is provided with a chess-hopper, J', which communicates with the eye of a suction-fan, K.

Lis a similar air-trunk arranged on the discharge end of the machine and communieating at its lower open end with the discharge-spout g. The air-trunk L also extends upward and across the machine, and is providedy with a similar chess-hopper, L', which communicates with the eye of the fan K on the opposite side of the fancase K. The air-trunks J and L are provided with suitable valves or dampers whereby the air currents through the air-trunks are regulated and controlled.

m is an opening formed in the casing in rear of and below the head of the inclined screen, and n are openings formed in` the top of the casing above the screen, and communicating with the eye of the fan by spouts n'. The openings a are regulatedV or entirely closed by valves n2.

O is the driving-pulley, mounted on one end of the shaft f of the brush-cylinder, motion being communicated to the pulley O by a suitable driving-belt.

P is a pulley mounted on the opposite end ofthe shaftf, and P asimilar pulley mounted on the shaft d2 of the scouring-cylinder.

Q is an idler-pulley arranged above the pulleys P P', and mounted on au arbor, q, se-

[cured to an upright standard, R, which is i fastened to the cross-hars a' of the frame of the machine by bolts r. The standard R is provided with elongated openings or slots r', through which the bolts r are inserted, and whereby a vertical adjustment can be given to the idlerpulley when desired. S represents an endless belt which runs over a pulley, s, mounted on the fanshaft. The belt S runs from the pulley s down under the pulley P, thence over the idler-pulley Q, thence down under the pulley P', and up to the pulley s on the fau-shaft, whereby motion is communicated from the brush-cyl inder to the scouring-cylimier, and then to the fan, and the brush and scouring cylinders are caused to revolve in the same direction.

t is a pulley mounted on the opposite end of the shaft d2, and T a pulley mounted on the arbor or shaft of one of the sprocket-wheels of the elevating mechanism.

T isfan endless belt running from the pulley t over the pulley T, whereby motion is communicated from the. shaft d2 to the pulley T, and thence to the elevating mechanism.

u is a pulley mounted on a shaft, u', which yis journaled in suitable bearings secured to the top of the machine. y

u? is a pulley mounted on one end of the fanshaft, and ai an endless belt running from the pulley u2 over the pulley a, and communicating motion to the shalt a'.

v represents a connecting-rod secured at one end to the shoe I-I, and its opposite end connected to an eccentric or cam mounted on the shaft u', whereby a reciprocating or vibratory movement is imparted to the shoe H.

The material to be separated is fed upon the shaking-shoe I-I, and any straw, sticks, or 1 other foreign matter contained in the grain are separated therefrom by the riddle or screen lz', and the grain passes through the spout i into the feed-spout I. From the feedspout I the grain enters the wind-trunk J, where the light grains or chess are caught by the. aircurrent in the trunk J, and are carried upwardiu the airtrunk and deposited in the chess-hopper J'. The grain that drops out ot' the air-current falls onto thespoutjand into the machine, and is carried upward by the elevating mechanism, and deposited upon the inclined screen B. From t-he screen B the grain falls into the scouring-trough D', where it is subjected to a constant rubbing or scouring action between thecorrugated surfaces of the `scouring-cylinder' and trough. The material is then carried by the action of the scouringcylinder to the outside of the trough, and caught up by the brush-cylinder and conveyed IOO IIO

by the action of the brush between the brush and the concave F', and deposited on the bottom of the machine. This operation is repeated a number ot' times as the material is gradually moved from the feed side to the discharge side ofthe machine by the angle-plates or inclined boards b. The material which has reached the discharge end ofthe machine is discharged from the brush-cylinder and concave upon the discharge-spout g, where it escapes into the air-trunk L, andthe outer ber ofthe grain and any other impurities contained in the grain which have been removed bythe action of the scouring-cylinder and brush-cylinder are carried upward by the air-current in the trunl `L and deposited in the hopper L. The clean grain is discharged at the bottom of the air-trunk L. By means of the openings in in the casing, and the openings n, which communicate with the eye of the fan, a current of air is caused to circulate through the screen, and the grain, as it descends on the screen, is subjected to this air-current, whereby the grain is cooled and the fluff of the berry rcmoved.

w represents a detlecting-board arranged near the head ofthe inclined screen, whereby the grain as it falls from the buckets c is deflected on the head of the screen, and w is a similar board arranged below the tail of the screen for guiding the material from the screen into the scouring-trough.

w2 is a check-board arranged between the scouring-cylinder and the brush-cylinder, to receive the impact of the material as it escapes from the scouring-cylinder.

My improved machine is very simple and compact in construction, and forms a very complete and effective separating and scouring machine for cleaning wheat and other grain.

I claim as my invention- 1. The combination, in a grain separator, of an inclined screen, an elevating mechanism arranged with its descending and ascending sides on opposite sides ofthe inclined screen, a shaking-shoe which sifts the grain before entering the machine, and an air-trunk which receives the sifted grain from the shoe and effects a separation of the light grain and chess from the heavy grain before it enters the machine, substantially as set forth.

2. The combination, with an inclined screen, of deicctors whereby the grain is moved laterally across the machine, a sconring-cylin. der and concave which receive the grain from the screen, and an elevator whereby the grain is returned to the head of the screen after it has passed through the scourcr, substantially as set forth.

3. The combination, with an inclined screen, of a scouring-cylinder and concave, whereby the grain is scoured after it leaves the screen,

a brush-cylinder and concave which receive the grain after it has passed through the scourcr, and an elevator which returns the grain from the brush mechanism to the head ot the screen, whereby the grain is repeatedly screened, scoured, and brushed in passing through the machine, substantially as set forth.

The combination, with an inclinedscreen, of deiiectors whereby the grain is moved laterally across the machine, a scouringcylinder and concave which receive the grain from the screen, an elevator whereby the grain is returned to the head of the screen after it has passed through the screen, and a separating air-trunk which receives the grain after the operations of screening and scouring are completed, substantially as set forth.

5. The combination, with an inclined screen, of a scouring-cylinder and concave receiving the grain from the screen, a brush-cylinder and concave receiving the grain from the scourcr, an elevator whereby the grain is returned from the brush mechanism to the head of the screen, and a separating aintrunk to which the grain is finally discharged from the brush mechanism, substantially asset forth.

6. The combination,with the inclined screen, of a scouring-cylinder and concave receiving the grain from the screen, a brusl1-cylinder and concave receiving the grain from the scourcr, an elevator whereby the grain is returned from the brush mechanism to the head of the screen, a separating air-trunk to which the grain is finally discharged from the brush mechanism, and a preliminary separating airtrunk through which the grain passes before it is subjected to the operations of screening, scouring, and brushing, substantially as set forth.

7. The combination, in a grain separator. ot an inclined screen, B, an elevating mechanism, C, arranged with its ascending and descending sides on opposite sides of the screen, an inclosing-casing provided with air-inlet openings m in its side, and outlet-openings n in its top, and a fan, K, having its eye communieating with the openings n', whereby a current of air is drawn through the incline screen, substantially as set forth.
